Changes that could make Test cricket more interesting

Installing a helmet-mounted camera

This has also been experimented with in the past, and a few batsmen have said it does not affect their concentration. So this could potentially get the green light in Test cricket.

This look at the cricketer's perspective could make things interesting for fans.
